摘要

以聚乙二醇二胺1,1′-二取代二茂铁为尺寸互补位点，与β-和γ-环糊精(CDs)自组装合成了低覆盖率的伪聚轮烷(pPRs)。用N-(三苯基甲基)甘氨酸(Trt-Gly-OH)对β-CD pPRs进行端盖后，生成了精确的β-CD[3]聚轮烷(PR)。然而，从末端盖帽的γ-CD pPR中鉴定出了意想不到的γ-CD [2]PR和预测链折叠链γ-CD pPR。

Size-complementary effects of PEG diamine 1,1’-disubstituted ferrocene on incorporations of β- and γ-cyclodextrins and syntheses of poly(pseudo)rotaxanes with lower coverages therefrom

Poly(ethylene glycol) diamine 1,1’-disubstituted ferrocene was utilized as a size-com-plementary site to synthesize lower coverage pseudopolyrotaxanes (pPRs) from self-assemblies with β- and γ-cyclodextrins (CDs). After end-capping β-CD pPRs using N-(triphenylmethyl)glycine (Trt-Gly-OH), an exact β-CD [3]polyrotaxane (PR) was created. However, an unexpected γ-CD [2]PR and a predictive chain folded stranded γ-CD pPR were identified from end-capped γ-CD pPRs.

期刊介绍： The Journal of Inclusion Phenomena and Macrocyclic Chemistry is the premier interdisciplinary publication reporting on original research into all aspects of host-guest systems. Examples of specific areas of interest are: the preparation and characterization of new hosts and new host-guest systems, especially those involving macrocyclic ligands; crystallographic, spectroscopic, thermodynamic and theoretical studies; applications in chromatography and inclusion polymerization; enzyme modelling; molecular recognition and catalysis by inclusion compounds; intercalates in biological and non-biological systems, cyclodextrin complexes and their applications in the agriculture, flavoring, food and pharmaceutical industries; synthesis, characterization and applications of zeolites. The journal publishes primarily reports of original research and preliminary communications, provided the latter represent a significant advance in the understanding of inclusion science. Critical reviews dealing with recent advances in the field are a periodic feature of the journal.
